Press and public
June 2025 – Motivated by an aqua pura presentation, the third grade class at OBS Wollerau carried out a very successful fundraising campaign.


When a certificate of appreciation arrived from the directors of St Edwards School in Uganda, the pupils in Year 3 at OBS were rightly proud of their contribution.


aqua pura is promoted to Rotary District Grant!
The topic of ‘Water – a vital yet scarce resource’ is a high priority for Rotary. The result of the vote by all RCZI members at the project workshop: aqua pura projects in Uganda and one other project were selected from eight projects and will continue to receive support. aqua pura has been awarded a Rotary District Grant!
Contact has been established with Rotary Mukono (Uganda). The aim is to receive up to USD 15,000 for the implementation of selected projects in Uganda. The application must be submitted by March 2026 and the projects will start to be implemented from July 2026.
Aqua pura would like to thank Rotary Zurich Circle International, especially Ms Daniela Beyrouty and Mr Markus Simmler, for their continuous and generous support. We look forward to continuing our collaboration.
December 2024 – Special fundraising event at Lindenhof in Buchberg

An original idea by Susanne and Markus Simmler, owners of the Lindenhof in Buchberg and members of aqua pura, led to a donation of CHF 422 to aqua pura at the end of December 2024. The donation was based on a contribution of CHF 1 for every 500 ml of tap water ordered by guests at the Lindenhof.
Thank you, Susanne and Markus, from aqua pura.
June 2021 – The topic of clean drinking water in the school in Düdingen, Canton Fribourg Switzerland
The school subject "clean water" prompted class 8ha in Düdingen to act. Although the planned presentation by aqua pura had to be postponed, the pupils started to implement their plan immediately. They designed a flyer, made many beautiful and useful items and sold them to friends, acquaintances and interested visitors to their information stand. They handed over the proceeds of CHF 1,814.00 from the sale and another CHF 550.00 from donations to aqua pura to support our projects. In total, the students donated CHF 2,364.00. A great success and convincing proof that together we can achieve a lot. Many thanks to all!

As soon as the situation allowed, our President, Roland Widmer, seized the opportunity. During a presentation at the school in Düdingen, he showed the globally precarious situation and the challenges associated with water shortage and water hygiene. 39 pupils and teachers showed great interest in the presentation. The subsequent discussion was correspondingly stimulating and informative. And as we were able to experience: these students do not leave it at words!

UN World Waterday and aqua pura
aqua pura has set itself the goal of raising the awareness of youth in schools on the topic of clean drinking water.
February 2017 and June 2018: In context with the teaching subject "clean water" at the Bilingual School in Pfäffikon, Canton Schwyz, aqua pura was invited to present the projects and to address the water problems and hygiene around the world in a two-hour lecture with pictures and film. Roland Widmer, president of aqua pura, was able to inspire the approximately 70 young people. The pupils and teachers listened attentively to his speech and took an active part in the discussion.

June 2010 – The world market Oerlikon was a success
The world market at the market square in Oerlikon in Zurich of 11th June and 13th August 2010 was a great success for aqua pura and also something new for the many visitors at our booth. They had never seen anything about UV-C radiation as a bacteria and virus killer. Our stand - as the picture shows - presented itself as a point of attraction.
